SPECIFICATION forming part of Letters Patent No. 532,059, dated January8, 1895.

' I Application filed February 19, 1894. Serial No. 500,776. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN W. HAYWARD, a subject of the Queen of GreatBritain, residing in the city of Cincinnati, in the county of .5Hamilton, State of Ohio, have invented a new and useful ImprovementinCoupling Devices, of which the following is a specification.

. My invention relates to devices for coupling vehiclesand ismoreespecially adapted IQ for use on freight cars, althoughit. is alsoadapted to be used on passenger cars, street cars-and other likevehicles.

My invention consists essentially, first, of mechanism, for coupling andreleasing cars, I operated from the top of such cars or from the groundbeside them without endangering life or limb by standing between thecars while either coupling or uncoupling the same; and second ofmechanism for guiding the connecting link or part of one car to engageor take into the proper part of a car to be coupled thereby, alsoadapted to be operated from the top or side of the cars. Referring 'tothe drawings: Figure 1. is a side elevation of the ends of two carsabout to be coupled. Fig. 2. is a detail of the draw-v bar andcoupling-pin. Fig. 3. is a detail illustrating the lever motion. Fig. 4.is a bottom plan view of a part of a car. Fig. 5. is an end elevation.

A, A are freight cars. B, B are draw-bars which are attached to thefreight cars in the usual manner and provided with hollow ends orbell-shaped open- 5 ings b, b.

C is a coupling-link ofthe usual construe tion.

D,D are coupling-pins mounted at d, d by a ball and socket connection orjoint in lever arm E, E pivoted at e, e to a bracket suspended from thebottom of the car or any suitable part of the frame, having a weight E,E

on the end thereof. This weight is adapted to be moved along the leverarm and clamped .5 in position by means of set screws 6 a This weight iscounterpoised which tends to force the coupling-pin D D through thedraw-bar B, B to hold the link connecting the drawbars. A spring may beused in place of the 'weight if desired. 1

To force the coupling-pin out of its position in the draw-bar B to,release the link (shown by the position pin D), I'ernploy a compoundlever F which extends from the top of the car and consists of lever fpivoted at 1 to leverf' pivoted at 2 and pivotally connected at-3 tolever f pivotally connected at at to lever f pivoted at 5 and rigidlyconnected at 6 .to a crank shaft G extending under .the car and providedwith a crank g and handles g. Rigidly connected to crank g is a cam-armH adapted to bear upon the lever arm E in such a way that when lever fis pressed downwardly by the foot or hand the crank shaft G is rotatedthereby. This arm I-I forces the coupling-pin out of its draw-barreleasing the link at the same time it raises the weight ,E which tendsto return the pin to its locking position as soon as arm H is released.,Arm H is so arranged that when the pin has been thrown fully out ofengagement with the link arm H will stay in position by friction untilit is released by hand or automatically by a part of the mechanismhereinafter to be described. A stop 6 on bar, E limits the movement ofarm H'in'one direction. In the guide 6 e which depends from the draw-baror bottom of the car and in which the lever arm E moves is a lockingdevice or plate-J having a crank arm j rigidly attached 'to it so thatwhen the crank arm is turned this locking plate moves with it to lock orunlock lever bar E and hold the coupling-pin securely in position or torelease it as may be. This crank arm j is connected by bar 72. with thearm H. observed that when the arm H is operated to bear upon the leverarm E and release the coupling-pin it will through the connections namedforce the locking plate out of engagement and allow the bar E to rise atthe end having the Weight upon it and-when the arm H releases itsbearing force and takes the position shown on the attachment to draw-barB, it will force the locking plate into position 9 whereby thecoupling-pin is locked securely 5 By this arrangement it will be Y inits position in the hollow end of the drawbar.

A buffer-barK extends through the drawbar B (being withdrawn intodraw-bar B and consequently not shown)-and extends without the openingI) and is connected with the crank g on the shaft G. When two cars arecoupled the bar K strikes the draw-bar on either car and forces it backunder the car, turning the crank g which releases the arm Hautomatically, and the coupling-pin will be forced into positionimmediately by means of the weight on the end of the lever E.

The great objection in using a movable link and coupling cars from anyposition than standing on the ground between the cars has been that thelink could not be guided into 1 the proper receiving part of the car tobe coupled. I accomplish this by means of the plate L within the openinginthe draw-bar.

This plate is pivoted at Z by being rigidly secured to a rock shaft Mextending under the.

car andprovided with handles mat the sides of the cars. This plate L maybe lifted or lowered so as to lift or lower the link resting on it inthe opening of the draw-bar. desired to operate this plate from the topof the car it may be done by means of the compound lever N, consistingof lever 12. pivotally connected with lever n which is pivoted at 8 andpivotally connected at 9 with lever n passing through the .guide 0pivotally and connected at 10 with lever 01. and pivotally connected at12 with lever n which is rigidly connected with the rock shaft M at 12?.When the lever 01. is pressed downward by the foot or hand through the;connections named it rocks the shaft M which;

swings the plate L as desired. The plate Irv is provided with a hole lthrough which thev coupling-pin moves freely.

The operation of my coupling device is.

simple. The brake'man may stand at the brake-wheel on the top of the carand operrate the brake as the car approaches the car.

to which it is to be coupled. He lifts the link by pressing downthelever n and the bar K will automatically release the arm H and thecoupling-pin will be instantly forced into position by the weight onthis lever arm. If he wishes to uncouple the cars or set the pin foruncoupling, he merely presses down the lever f and leverf operatesthrough the com pound lever F, the crank shaft G, and camarm H, which inturn releases the locking plate J and at the same time forces the leverarm E and releases the coupling-pin.

car on the train by a single act.

I claim-- If his pivoted at 11 by the link is secured in position in thehollow end of the draw-bar, such pin being mounted in a lever armwhereby the pin may be forced into position in the draw-bar or withdrawntherefrom, a crank shaft provided with a cam-arm adapted to engage andoperate the lever arm in one direction (a weight tending to force it inthe opposite direction), and a compound lever F, consisting of levers f,f, f and f 3 and adapted to rotate the same, substantially as and forthe purpose described.

2. The combination in a car coupling device of a drawbar having a hollowend, a link adapted to take therein, a coupling-pin whereby the link issecured in position in the hollow end of the draw-bar, such pin beingmounted in a lever arm whereby the pin may be forced into position inthe draw-bar or withdrawn therefrom, a shaft provided with a cam-armadapted .to engage and operate the lever armin one direction, (a weighttending to force it in the opposite direction,)

means for rotating the shaft, and a plate for 0 locking the lever arm,such plate being connected with and operated the cam-armshaft,substantially as and for the purpose described. p
